Cavitation Light Emission and Cavitation Erosion

Journal of The Japan Institute of Marine Engineering, 2008
Cavitation bubbles emit a very weak light due to bubble collapse. It is expected that the light emission may be closely related to cavitation erosion. In order to confirm the relationship between the erosion damage rate and the light intensity, experiments were performed for a water orifice cavitation flow. A circular pipe was used and water-cavitation

Prediction of Cavitation Intensity and Erosion Area in Centrifugal Pump by Using Cavitating Flow Simulation with Bubble Flow Model

Journal of Fluid Science and Technology, 2010
We developed a numerical simulation code and a method of estimation for predicting the cavitation erosion in pumps. Cavitation erosion is closely related to cavitation intensity based on bubble dynamics.

Studies on Cavitation Erosion

Chemical engineering, 1967
内径52.9mmの円管の中心部に置かれた球に生ずるギャビテーション・エロージョンについて, 最大流速15m/sec (Re=1,200,000). 球径9.50～33.00mmの範囲で試験を行なった。高速度写真撮影 (10.000コマ/sec) ならびにストロボスコープによる観察の結果, 球の後部に発生する気泡の挙動に関して3つの流域があること, 鋼球を用いた侵食試験では, これらのうち最も高速の流域でかえって損傷速度が減少することを確め, またその理由をも明らかにした。

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...
